This registers the new fchmodat4 syscall in most places as nuber 451,
with alpha being the exception where it's 561. I found all these sites
by grepping for fspick, which I assume has found me everything.

In linux-6.5-rc1, number 451 is used for __NR_cachestat, the
next free one at the moment is 452.

Unfortunately, you still also need to change __NR_compat_syscalls
in arch/arm64/include/asm/unistd.h. Aside from these two issues,
your patch is the correct way to hook up a new syscall.
